Specification of Letters Patent.

Patented Nov. 20, 1917.

Application filed January 11, 1917. Serial No. 141,824.

To all whom it may concern:

Be it known that I, JACOB J. SMITH, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in an Adjustable Oil-Gas Burner; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,

- and to the numerals of reference marked thereon, which form a part of this specification.

with respect to the stove holes without necessitating any changes in the connections of the burner, nor requiring auxiliary piping connections for the purpose. The burner assembly is further adjustable as a unit to Various heights, so that the flame is properly positioned for most efficient use beneath an article disposed on or above the stove hole.

It is an object therefore of this invention to construct a hydro-carbon burner wherein combustion of gas formed due to carburetion of entering air, takes place at three different points, one pointof combustion serving to heat the fuel supply to facilitate the carburetion of the entering air by the oil.

It is also an object of this invention to construct aIburner assembly embracing two hydro-carbon'burners for use in a stove, and

adjustable for proper position with reference to the stove holes, and with a third burner for heating the fuel prior to carburetion of the air thereby, and with all three of said burners communicating with the carbureting means of the burner to receive gas therefrom for combustion.

It is a further important object of this invention to provide a simple and compact burner assembly, which may be readily mounted in practically any type of stove,

' and easily adjusted for use therewith.

Further objects will be apparent from'the disclosure in the drawings and specification. The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

As shown in the drawings:

Referring first to Fig. 1, the stove is denoted as a whole by the reference numeral 1, and is provided with a top plate 2, and a horizontal supporting grating 3, near the lower portion thereof. The burner comprises a horizontal rearwardly disposed fuel mixture pipe l, the ends of which are curved .upwardly and a short inlet air pipe 5, the

ends of which are directed downwardly, and said respective pipes are connected to one another by frame bars 6. Said pipes 4. and 5, are also rigidly connected andcommunicate with one another through a horizontal pipe extension 7, formed integral therewith and communicating centrally with each thereof. Screens 10, are mounted in the downwardly directed open ends of the inlet pipe 5, as clearly shown in Figs. 9 and 10. A cleaning hole 11,'i's provided, as shown in Fig. 8, in the inlet pipe 5, and a pivoted closure 12, is normally disposed in closed position thereover, but may be swung upwardly and to one side out of closed position to permit access to the interior of the pipe.

Secured into the upwardly directed end of the pipe member 4, are short pipe sections 13, and threaded adjustably on the upper reference numeral 28.

ends thereof are burner plates 14, as shown olearlyin Fig. 5, each being apertured and provided with a screen 15, fitting over the upper end of the pipe section 13, to which it is connected. Each burner plate is provided with a shutter 16, actuable by a handle 17, and having a pin 18, slidable in a slot 19, in said plate, to open and close the aperture in said plate leading from the pipe section 13. A burner ring 20, is secured by means of screws 21, upon each ofthe burner plates 14:, and together with said plate, affords an annular compartment for the gas flowing into the burner from the pipe section 13, and each of said burner rings is provided with a plurality of apertures 22, through which the gas flows for ignition and combustion.

Communicating centrally into an extension on the central upper portion of the inlet pipe 4, is a pipe section 28, which is formed integral with the forwardly and downwardly curved burner pipe 24, having a plurality-of burner slots 25, in the upper surface thereof. Said burner pipe 24, is provided with two upright yoke members 26, in which is supported a kerosene or other hydro-carbon fuel pipe 27, which is doubled back upon itself, as clearly shown in Fig. 8, with the lower end thereof denoted by the Said lower end 28 projects through an opening in the top central portion of the inlet pipe 5, and extends downwardly therethrough, and is provided with a small hole or aperture for exit of the fuel therethrough into said inlet pipe to carburet the entering air.

Formed on the'upper. portion of the pipe member 5, surrounding the point of entrance of the fuel pipe 27, is a pan or tray 29, and also secured or formed beneath the straight portion of the burner pipe-24, is another pan or tray 30. As shown clearly, in Figs. 3

and 4, supporting legs 31, are attached by means of screws or bolts 32, to the end portions of the frame bars 6, of the burner as' sembly, said. legs being providedwith vertical slots therein to permit adjustment to elevate the burner assembly to different heights.

The operationis as follows:

Fuel is supplied to the burner through the fuel supply pipe 27, and preliminary to operation of the burner, a small quantity of fuel is introduced into the respective pans 29 and 30, and ignited. The heat of the burning fuel in said pans 29 and 30, serves to heat the fuel pipe 27, as well as the burner pipe 24:, thus causing a primary generation of fuel gas in the pipe 27, and this fuel gas passes out through the aperture in the lower end 28, of said pipe. car-,

bureting the air which enters through the screens 10, of the inlet pipe member 5. The gas mixture flows trough the pipe 7, and

upwardly through the pipe section 23, into the heated burner pipe 24, .and may be ignited as it passes through the burner slots 25, thereof. The burning gas ignited at the exit slots 25, of the burner pipe 24:, servesto heat the fuel in the supply pipe 27, thus" Access to the burner pipe connections may be had through the shutter 12, for cleaning the same, if necessary. The burners 20, are adjustable horizontally to various positions through being swung on the pipe section 13 as pivots, as shown in dotted lines in Fig. 2, in order to readily adapt the burner assem- -bly for use in a stove so that the burners may be properly positioned beneath the apertures in the topplate of the stove. Furthermore, the burner assembly is adjustable as to height to bring the burners at the proper distance below the flame apertures of the stove by adjusting the legs 31, after loosening the screws or bolts 32, therefor.

I claim as my invention:

1. A burner assembly, comprising a fuel generating means, a plurality of burners independently adjustable in a horizontal plane, and a support carrying said generating means and said burners and on which they are adjustable vertically.

2. A burner assembly, comprising a fuel generating means, a plurality of burners independently adjustable in' a horizontal plane, frame bars upon which'said parts are mounted, and legs supporting said frame bars and upon which they are adjustable vertically.
